摘要
利用相位式测距原理的激光测距仪,在无合作目标近程测距(0.2~100 m)时,采用可见激光瞄准,这对激光光斑有非常高的要求,光斑在被测目标上的大小即激光准直程度,直接影响测距精度和测程,因此,光学系统的设计就非常重要,解决这样的问题对提高无合作目标的测程与精度是非常有益的。
The hand-hold laser rangefinder which adopts the laser phase ranging principle makes it possible to collimate laser without co-operant target short range measurement (0.2-100 m). The design of laser optical system is of great importance because laser collimation has a high demand on the laser spot whose collimation degree affects the accuracy of laser ranging. Therefore, a well - designed laser optical system is quite beneficial for the improvement of the measurement range and precision of non-co-opera-tive target.
